Exam 9: Tcp/ip Transport Layer Protocols

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -the process of acknowledging multiple packets with a single acknowledgment

Which of the following is detected whenever three or more duplicate ACK packets (known as a triple-ACK) or timeout events occur, and timeout events are considered more serious than duplicate acknowledgments?

List the fields contained in the UDP header.

Which of the following provide the simplest kind of transport services because they simply package messages, taken as is from the TCP/IP Application layer, into datagrams?

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -a queuing area used to hold incoming and outgoing TCP packets

Which of the following defines the length of the packet from the UDP header to the end of valid data (not including any data link padding, if padding is required)?

Which of the following does TCP support, which is a management method for data transmission used to determine the amount of unacknowledged data that can go out on the wire from any sender?

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -a method for determining when to stop resending data across packets

____________________ defines the range of numbers that identifies dynamic ports.

When the Protocol field of an IP header contains the value 17 (0x11), the UDP header follows the IP header. Indicate the answer choice that best completes the statement or answers the question.

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -an amount of time that a TCP host must not use connection parameters after closing down that connection

UDP is the only connectionless TCP/IP protocol at the Transport layer.

UDP offers connection-oriented services with sequencing, error recovery, and a sliding window mechanism.

Match each item with a statement below. a.timeout mechanism b.temporary port c.Time Wait delay d.TCP buffer area e.retransmission timer f.Nagle algorithm g.Sequence number tracking h.acknowledgment i.windowing -a method stating that when small packets are sent but not acknowledged, no further packets shall be sent

TCP has four defined congestion control mechanisms to ensure the most efficient use of ____________________ along with quick error and congestion recovery.

Briefly describe the TCP startup connection process.

Briefly discuss the type of tasks typically handled by connectionless protocols.

Dynamic ports are used as which of the following for specific communications while they are underway?

Briefly discuss four limitations of UDP.

The ____________________ window is always the lesser of what the network and receiver can handle.
